Review on the preparation of high value-added carbon materials from biomass

Biomass is considered a promising carbon containing solid renewable resource, which has the characteristics of environmental protection, large total amount and wide distribution. Biomass can be used to produce bioenergy and green chemicals, and also act as the raw material for advanced carbon materials. This review summarized the preparation technologies of high value-added carbon materials (HVCMs) such as activated carbon, carbon nanotubes, carbon nanofibers and graphene in recent decades, summarized the preparation methods, properties and applications of HVCMs, and made an in-depth study on the raw material selection, preparation methods, reaction conditions and formation mechanism of biomass-based high value-added carbon materials (BHVCMs). Finally, the existing problems and future work were put forward to help the large-scale preparation of BHVCMs and promote the resource utilization of biomass.
